CONDENSER.

Application filed January 11, 1924. Serial No. 685,528.

To all whom it may concern:

. Be it known that I, EINAR A. JOHNSEN, a citizen of the United States, residing 'at Mountain Lakes, Morris County, and State of New Jersey, have invented an Improvement in Condensers, of which the following is a specification.

My present invention relates to a surface condenser and more particularly to that type of single pass condensers adapted for use ing turbine practice, although, as will be understood, the invention is not necessarily limited to the single pass type of condenser or to being employed as a condenser for a steam,

turbine. Condensers of the type to which my invention relates are necessarily relatively large in order to provide for the necessary capaclty of the apparatus and it is custom ary to provide support plates at intervals for maintaining the tubes in position in the shell to reventthe tubes from sagging and to guard the same against unnecessary vi- .brations. These support plates divide the interior of the condenser shell intoa. plurality of transverse compartments. Ob'-' viousl the-number of support plates necessari y employed depends upon the length of the tubes and the size of the condenser.

In condensers of this ty e considerably more steam is condensed at tiie end at which the cold circulating water is admitted and there is comparatively little condensing ef- I ,feet produced at the opposite end of the the apparatus;

' condenser where the circulating water leaves In this practice the steam enters the condenser at a relatively high velocity and in order'to distribute the steam proportionately to the condensing capacity in allparts of the condenser it 1s necessary to place" the exhaust steam inlet adjacent the circulating water inlet of the condenser and also to provide a plurality of adjustable bafiie or directing plates to distribute the steam into the several compartments of the condenser so that each section thereof will operate efliciently. In so doingI have also found it necessary to arrange an outlet in each of the several compartments for'the .condensate and the non-condensable gases and to employ a suitable means for regulating each outlet in order to cause every tube injeach compartment-to do its share of the work whereby some of the steam as admitted to eaeh compartment reaches the lowermost tubes before being condensed, and as will net 25 to close the water box.

he understood the construction and useof surface for any required service than those now ordinarily employed.

The condenser made in accordance with my invention will be hereinafter more particularly described in conjunction with the. accompanying drawings, in which,-

.Fig. 1 is a side elevation and partial sectiOl of my improved condenser apparatus, an

F ig. 2 is .an end view and partial transverse' section of the same on an enlarged scale; v

Referring to the drawing the condenser shell is indicated at 10. This is made in the customary manner by being provided at the ends thereof with flanges 11 and 12. Ad-. jacent the fl-angell there is a tube plate 13 and similarly adjacent the flan e 12 there is a tube plate 14; These tube p ates and the water boxes hereinafter described are secured together and to their respective condenser shell flanges by bolts or otherwise in the customary manner. Extending through the condenser shell and suitably connected at their ends in the tube plates 13 and 14 there isa plurality of tubes 15. At one end of the condenser there is a water box 16. This is provided-with flanges 17 and 18, the fglirmer being connected .to the adjacent tube p ate and flange of the condenser shell and the latter being connected to the usual bon- 16 is also fitted with the usual inlet nozzle 21 for the admission of the circulating water. As illustrated this' circulating nozzle is at the lower end of the box and in an offset position: However, as will be un derstood this inlet nozzle may be placed in 9,

any position.

At the opposite end the condenser is fitted with a water box 22. This is provided with flanges 23 and 24, the formerbeing connected to the tube plate 13 and the adjacent end flange of the condenser shell, as hereinbefore I stated, and the latter is connected to abon- This water box may also be provided with a plurality of hand-holes each of which is n ll closed by a hand hole cover 26. The waterbox 22 is furthermore provided with the usual circulating water outlet nozzle as indicated at '27, This oulet nozzle as illustrated is at the top of the water box, but, as will bev understood, may be placed in any position relative thereto.

Interiorly the condenser shell is divided into a pluralit'y of compartments by partition walls 28. The condenser tubes 15 pass through and are supported by these partit'onwalls which extend transversely across t e'condenser shell. The condenser shell is also provided preferably at the top thereof, as shown in this instance, with a nozzle 29 adapted to be connected to the exhaust pipe from a turbine or other translating apparatus. At the upper ends of the partition walls 28 or connected to other parts of the sameadjacent the exhaust steam inlet nozzle I employ bafile plates indicated at 28, 29'. These bafile plates are of any suitable configuration and are preferably hinged to the extremities of the partition walls adjacent the exhaust steam inlet and may be adjusted either exteriorly or otherwise to the required position for directing predetermined quantities of steam to the several compartments of the condenser. Any means, however, friay be employed for mounting and adjusting these bafile plates for thus directing the passageof the exhaust steam.

The number of partition walls and the resultant compartment into which theinterior of the condenser shell is divided may be varied as occasion requires, it being within the scope of the invention to employ any number of these partition Walls and compartments. As illustrated. I have shown two partition walls dividing the interior of the condenser into three compartments of substantially equal size. In the bottom of the shell of thecondenser there is anoutlet for,-

the condensate and non-condensable' vapors from each compartment. As illustrated therefore, the bottom of the shell is provided withbosses 30, 3-1-and 32 centrally of which are the outlets 33, 34 and 35 respectively. Each of these condensate outlets is provided with, a valve "for regulating. the passage of the condensate and non-condensable vapors therethrough. These valves are similar in construction and are indicated at 36, 37 and 38, one of the same being shown in. section.

- Each of these valves includes a valve body 39 having a valve seat 40 adapted to receive va valve 41 operated by a valve stem 42. The

valve stem 42 as indicated preferably passes through a suitable stuffing box 43 and is jo'urnaled in a bearing provided for this purpose in a yoke 44, while at its outer-end the valve'stem is fitted with a hand wheel 46 for turning the same to adjust the position of the valve relatively to its seat. It will be noted that the-yalve seat is preferably coniother connection which. as illustrated, communicates at one end 50 with a cooler for the gases and at the other end 51 to a condensate pump for disposing of the conden'sate.
